About the conversion level for Google Search traffic compared to Bing/Yahoo, I've long wondered what the difference is caused by. It's not only intentional tinkering with traffic quality on Google's side, or their creation of their own properties in the SERPs. The conversion level difference was always there, even back in the MSN Search days.
For some reason Microsoft's search demographic has always converted better for me, and Google has always seemed to be more about research and window shopping.
